Therefore, even if the depth of the three-way frame 100, that is, the length of the first vertical frame body 101 in the depth direction is long, it is possible to prevent the worker from putting his hands deeply into the landing side from the inspection opening 101e. . Thereby, a worker's hand can easily reach the housing 4 and work on the landing display device 1A can be easily performed.

  The housing holding / moving mechanism 5 supports the shoe main body portions 53a and 54a with respect to the rail main body portions 51a and 52a fixed to the first vertical frame body 101 in a state where the housing 4 is supported in the vertical direction. The housing 4 at the exposure position is moved to the hoistway side by being relatively moved to the back side in the depth direction. Therefore, the casing 4 at the exposed position can be moved in the depth direction while suppressing the catch. Thereby, the housing | casing 4 can be moved to a depth direction easily.

  In addition, since the housing 4 is moved from the exposed position to the hoistway side via the bracket 55, compared with a case where an operator grips the housing 4 and moves the housing 4 from the exposed position to the hoistway side, The gripping position of the worker can be on the hoistway side, that is, in the vicinity of the inspection opening 101e. Therefore, it is possible to prevent the worker from putting his hand deeply into the landing side from the inspection opening 101e. Thereby, since the worker can easily move the exposed position of the housing 4 from the exposed position to the hoistway side and move to the exposed position, the workability of the worker can be improved. Further, by fixing the bracket 55 to the first vertical frame body 101, the housing 4 can be held at the exposed position. Therefore, even if the user of the landing 200 depresses the operation unit 2, it is possible to suppress the housing 4 from moving to the hoistway side.

Therefore, as compared with the case where there is one positioning protrusion, the movement in a direction different from the depth direction of the casing 4 in which the protrusion holes 41h and 41i are inserted into the positioning protrusions 73 and 74 is restricted by forming a plurality of positioning protrusions. can do.

  Next, the inspection / repair work by the worker of the landing display device 1B according to the second embodiment will be described. In particular, the replacement work of the substrate unit 3 having the operation unit 2 will be described. In the replacement work of the landing display device 1B according to the present embodiment, the description of the same part as the replacement work of the landing display device 1A according to the first embodiment is omitted or simplified. In a state where the housing 4 is held at the exposed position, the insertion pins 61a and 62a are inserted into the pin holes and the pin holes 71a and 71b of the locking receiving portions 63 and 64, and the locking portions 61 and 62 are inserted. Is the locked state, and the locking side members 61c and 62c are the reference positions with respect to the support side members 61d and 62d.

  Next, when the worker removes the inspection lid 101f, as shown in FIG. 6, the worker pushes the casing 4 from the hoistway side toward the near side in the depth direction, and moves the casing 4 to the landing side (the same figure). Arrow P2). At this time, since the locking side members 61c and 62c are in contact with the locking receiving portions 63 and 64, the movement of the locking side members 61c and 62c on the near side in the depth direction is restricted. Therefore, the space between the support side members 61d and 62d and the locking side members 61c and 62c is contracted, and the locking side members 61c and 62c are compressed with respect to the supporting side members 61d and 62d while compressing the springs 61b and 62b. To move to the switching position.

  Next, when the casing 4 is moved to the landing side by an operator, the locking side members 61c and 62c move to the switching position with respect to the support side members 61d and 62d as shown in FIG. The claw is accommodated, the restriction of the movement of the locking claw by the claw receiving portion is released, and the locking portions 61 and 62 are switched from the locked state to the released state. At this time, the housing 4 does not contact the mounting frame 7 in the depth direction. Next, the worker grips the handle portion 43 by hand and pulls the handle portion 43 to move the housing 4 to the hoistway side (arrow P3 in the figure). At this time, since the locking portions 61 and 62 are in the released state, the insertion pins 61a and 62a can be removed from the pin holes and the pin holes 71a and 71b of the locking receiving portions 63 and 64.

  Next, an operator pulls the handle 43 toward the hoistway side, and removes the housing 4 from the vicinity of the inspection opening 101e in the frame body 101a or from the frame body 101a as shown in FIG. Position it on a desired position, such as placing it on a car. At this time, since no external force is applied to the locking side members 61c and 62c, the locking portions 61 and 62 move to the reference position while maintaining the released state by the urging force of the springs 61b and 62b. Next, the worker removes the housing lid 41c from the housing 4, removes the board portion 3, attaches a new board portion 3 to the inside of the housing 41a, and closes the housing opening 41b with the housing lid 41c.

  Next, the worker grips the handle portion 43 again, pushes the handle portion 43, and moves the housing 4 to the landing side. Next, the worker further pushes the handle portion 43 and inserts the positioning protrusions 73 and 74 into the protrusion holes 41h and 41i. Thereby, the positioning of the casing 4 in the vertical direction and the width direction with respect to the first vertical frame body 101 is performed. In a state where the positioning protrusions 73 and 74 are inserted into the protrusion holes 41h and 41i, the insertion pins 61a and 62a face the pin holes and the pin holes 71a and 71b of the latch receiving portions 63 and 64 in the depth direction. Next, the worker further pushes the handle portion 43 and inserts the insertion pins 61a and 62a into the pin holes and the pin holes 71a and 71b of the latch receiving portions 63 and 64, respectively. Next, the worker further pushes the handle 43 in a state where the locking side members 61c and 62c are in contact with the locking receiving portions 63 and 64, and the locking side members 61c and 62c are moved to the support side members 61d and 62d. On the other hand, it moves to the switching position, the locking claw protrudes, the movement of the locking claw is restricted by the claw receiving portion, and the locking portions 61 and 62 are switched from the released state to the locked state. Thereby, the housing | casing 4 is hold | maintained again in an exposure position. Next, the worker closes the inspection opening 101e with the inspection lid 101f.

  As described above, the landing display device 1B according to the present embodiment is such that the worker repeatedly presses the housing 4 from the hoistway side toward the landing side, so that the locking receiving portions 63, 62 of the locking portions 61, 62 are. Since the locked state with respect to 64 and the released state can be switched alternately, the housing 4 can be easily released from the held state. Accordingly, after the housing 4 held on the landing side is moved to the hoistway side, that is, near the inspection opening 101e by the housing holding and moving mechanism 6, the work on the housing inside 41a of the housing 4 is performed. Therefore, even if the depth of the three-way frame 100, that is, the length in the depth direction of the first vertical frame body 101 is long, an operator puts his hand deeply toward the landing side from the inspection opening 101e, It is possible to prevent the work on the inside 41a of the case 4 from being performed. Thereby, in the vicinity of the worker on the car, the hand can easily reach the housing 4 and work on the landing display device can be easily performed.
